v IMPROVEMENT IN MACHINES FOR.MAKIN(:`\l ROPE.

The Schedule referred to in these Letters Ptent 'and making part of the same.

To allA whom it may concern Be it known that l, WILLIAM G. PIKE, of Philadel phia, in the State of Pennsylvania, have invented a new and useful Machine for Making Ropes, of which machine the following is a specification.

In the annexed drawing- Figure 1 is a side elevation, partly in perspective, of the complete machine.

'lhe remaining figures represent details.

Figure v2 being a plan of that portion of the frame of the machine which encircles the bobble-disk carrier b, and contains the friction-rollers s', representing also a plan of said carrier and of the bobbin-disks (l, and a central aperture for the. upright main shaft of the machine.

Figure 3 is a plan of the gearing employed to drive the bobbin-disks.

Figure 4 is a plan of the drawing-rollers It k2 and their gearing,

Figure 5 is a plan ofthe auxiliary drawing-'rollers y'.

Figure 6 is a plan of the frame or plate c'.`

Figures 7 and 8 are plans :of the top and bottoln of the perforated guide f Figure 9 is aplan of the frame a, showing the cross-b1'aces.

Figure 1 0 Aisan elevation ofthe fra-ine. Figure 1l is a longitudinal vertical section of the hollow shaft c and inclosed shaft z, with bcvel-gcar`s attached to the latter.

a, gs. l, 2, 9., and 10, represents the frame of the mach ne.

b, -gs. l. and 2, is the bobbin-disk carrier, which is rigidly attached to the hollow shaft c.

d d d are the bobbin-disks, each of which is provided with three upright studs, e, arranged on each disk, so as to be cquidistant from the shaft j' of theforations, as shown in g. 2, for tubing the yarns;-

and the perforations may have short steel tubes inserted into them, if desired'. Each shaft f extends down through a hearing-box, t', tig. 1, and carries at its lower end a cog-wheel, j, figs. l and 3.

k, igs. l and 3, is a gear, which is provided with pioged on its ipper and lower lfaces, as shown in The wheel k is loose on the hollow shaft c, and it rests on friction-rollers, -Z, tig. 10.

The cogs on the lower face of the wheel- It are shown to be geared into the cog-wheels m and n, which are attached to shafts o and 1:, which extend through and have bearings in the legs of the frame, as shown in tig. 1.

The gear 'm isadjustablc ou the shaft p, so as to engage the gear k, as shown, when desired. It must be disengaged when gear fm is used.

q and r, iig. 1, are gears on the shaft 11.

s and t are gears, the former being attached to the verticalshai't a, and the latter to a horizontal shaft e, fig. 1, one end of which has a bearing in a leg of the machine, and the other .end in a box, w.

The shaft c carries at its inner extremity the bevel-gcar x, which engages the bevel-gear y, which is attached tothe lower `extremity of the shaft z, lig. 11.

a', fig. 1, is a bevebgear attached to the shaft 1); It engages the bevel-gear b', which is rgidly'attaohed to the hollow shaft c.

c', tig. 1, is a frame or plate, rigidly attached to the hollow shaft c, and having arms perforated 'at their extremities for the steel gathering-tubes fl.

c', fig. 1, is aguide-plate, preferably made in the hollow dish-shape shown.

It is provided witlrthree perforatious, two of which are shown in fig. 5.

f is a 'guide supported from the plate e', as shown, it being perforated with three guide-holes, g', figs. 7

and 8, for tubing the strands. Attached to the upper end of the shaft z, fig. 11, is the bevel-gear h', which engages the bevel-gear i', fig. 5, which is on the shaft of one of the rollers j.

t k2, figs. l and 4, are drawipg-rollers, which are grooved for the rope, as shown at m', and which carry gear-wheels n and o', respectively.

The roller carries the bevel-gear p', which eugages the bevel-gear q', which is attached to the upper end of the shaft u, iig. 1.

r', g. l, is a conc-pulley on the shaft o of the gear a. i

-s' s', figs. l and 2, are friction-rollers employed to steady the disk-carrier b.

t', tig. 1, is a .steel eyc or frame a.

To prepare the machine for operation, the bobbins g, g. 1, are supplied with rope-yarns.

The free ends of the three yarns from the bobbius of each disk, being passed through their proper pershort tube, set in the forat-ions in plates h, respectively, the said ends are brought together,- and the yarns thus made to form;-

a strand, which passes through its appropriate tube, of the three steel tubes d', one strand being passed through each of said tubes d.

The three strands are thence led through the three perforations in the guide-,plate e', one strand through each perforation, and thence through the three perforations in the gnidef, one strand through each perforation, the three strands intended to form the rope being at this point brought together and then passed through the eye t'iuto the groove nt of the drawing-rollers k1 and k2.

-Power is then applied to the shaft p, which, through the bevel-gears ak and b,tnrns the hollow shaft c of the 'machine rotating the disk-carrier l), with its several bobbin-disks d, the latter being rotated independently through the operation of their several gears-aud the stationary gear k in a direction opposite to the direction of rotation of the diskcarrier b, thereby twistingthe .yarns from .each set of bobbinsinto a strand.

It will be observed that the frame c', guide-plate c', guide f, and disk-carrier b, being 'all rigidly attached to the shaft c, are rotated by it simultane ously in one direction; also, that the rope, b'eing firmly heldin the groove m' by the pressure ofthe rollers k1 and It, is kept from turning while the three strands are brought together.

The union of the strands takes place as they leave the perforations in ther guide f', between which and the eye't. they get their iinal twist.

.The roller le?, being movedbythe action of the gears p', q', s, and fr, rotates in one direction, and the roller'k, being moved by the action of the gears o and a', rotates in an opposite direction.

These rollers thus serve the double purpose of drawing the rope from the twisting parts of the inachine as fast as it is iinished, and holding 'the rope, as above said.

. Lhe drawing-rollers may be lnade wholly of metal;

but I prefer to make them wholly of, or coat them lieve the drawing-rollers k1 and k2 of a portion .of'the` strain of drawing ofi" the rope.

In describing the operation of the gear k above, I have referred to it 'as being stationary; but when it is desired tovary the 4twist ofthe strands, t'. e., either to increase or diminish the twist, it becomesfnecessary to give rotary motion to the gear It, and when it is desired to increase Vthe twist, the gear k is caused to move in a direction .opposite to thedirection of rotation of the disk-carrier b-.by.v adjusting the gear lfm. so as to engage thecogs on Vthe lower face of the oear It.

When, on the' other hand,'it is desired to lessen the twist of the' strands, the gear m is disengaged from the gear k, and the gear n is put in motion by apply- -ing a belt to the pulley-cone r', thereby causing the disk-carrier b and the gear kto move in the same direction and diminishing the twist of the strands, as desired.v

The motion of the drawing-rollers k1 4and 7cz may be increased or. diminishedby employing gear-wheels of greater or lesser diameter in the ordinary mannel.

The drawinga'ollers k1 audit2 are adjustable toward or from each other toaccommodate ropes of different sizes, and the auxiliary drawing rollers j are similarly adjustable. f

lhe machine above described is intended for a rope of three strands, each of which' is composed of three yarns.

The number of yarns', however, may be increased by increasing the number of bobbins, and thenumberof strands` may be increased by correspondingly increasing the number of bobbin-disks d, guide-plates h, guide tubes d', and guide-holes in the guides e' on its own axis, in a direction which is contrary to the direction-of motion of the central shaft c, in combination with the shaft c, substantially as set forth, to twist the several strands intended to form the rope. l 2. The above-claimed mechanism, in combination with the frame or plate c', audits perforations, the guide-plate e and guide f', eye t, and rollers k1 k2, to draw and deliver. the rope and hold it -while the strands receive their tina-l twist andare united into a rope, substantially as set forth.

3.- 'lhe disk-carrier b and bobbin-disks d, in combination with the gears j and 7c, to give said disks'an independent rotary motion in a direction which is contrary to the direction of motion of the central shaft c.

4. rlhe combination of the cone-pulley fr', gear lr, and disk-carrier b, with their intermediate gearing for securing control over the independent rotary tno-y tion of vthe b obbin-disks.
